Title: Hot wire type air flowmeter
Inventor: AKAMATSU MASUO
IPC: G01F1/68
Filed: 1988-10-18
Abstract: PURPOSE:To obtain the high accurate air flowmeter with good response by performing associative control over the balancing variable resistance element of a resistance bridge circuit for temperature detection and the balancing variable resistance element of a resistance bridge circuit for flow rate measurement. CONSTITUTION:A heating resistance body 1 and an air temperature detection resistance 2 are paired and installed in an air flow passage, whose flow rate is to be measured. The resistance 3 functions as the current detecting resistance of the resistance body 1 and the resistance 7 functions as the current detecting resistance of a variable resistance element 5. A comparing circuit 4 detects the balanced state of the constant temperature control bridge circuit for flow rate measurement including the resistance body 1 and a control signal is supplied to a transistor (TR) 10 in response to the detection to control a current supplied to the resistance body 1. Variable resistance elements 5 and 6 are controlled associatively to the same resistance value at all times with the output of the comparing circuit 8. Then the element 6 constitutes a temperature compensation control bridge circuit with the resistance body 2 and constant current circuits 11 and 12 and the comparing circuit 8 generates the output according to the balanced state of this circuit, so the resistance value of the element 6 is controlled according to the resistance value of the resistance body 2, i.e., air temperature.

Title: Method for treatment of sludge
Inventor: FUJII WATARU
IPC: C02F3/12
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent offensive odor from being emitted or sludge from becoming difficult to dewater by alteration of the sludge in an excess sludge concentration tank and a sludge storage tank. SOLUTION: In an excess sludge-treating method, after organic sewage is biologically treated, the sludge is concentrated by a membrane separation sludge concentration tank provided with an aeration device, and the inside of a concentrated sludge storage tank is aerated. Carrying-out of concentration and storage of the excess sludge in an aerobic state prevents the sludge from becoming an anaerobic state and can avoid emission of offensive odor and proneness to difficulty in dewatering the sludge by change of properties of the sludge. Thereby the state of offensive odor in a sewage treatment facility is greatly improved. The peculiar offensive odor that anaerobic sludge emits is greatly reduced, even when the anaerobic sludge is dewatered by a mobile dewatering vehicle.

Title: Ink jet head
Inventor: YONEKUBO SHUJI
IPC: B41J2/14
Filed: 1988-10-17
Abstract: PURPOSE:To suppress variation in ink flying characteristic due to environmental temperature change by composing a pressure generating member of a laminated structure of at least two or more members having different thermal expansion coefficients, and reducing the coefficient at the nozzle forming member side with respect to the neutral plane of the member. CONSTITUTION:Since the thermal expansion coefficient of a nickel layer 14 of a metal layer is larger than that of a piezoelectric element 13 in a pressure generating member 15, when environmental temperature including ink 16 is raised, the member 15 is displaced to the element 13 side by means of its bimetal effect, and a gap between the member 15 and a nozzle forming member 11 is narrowed. On the other hand, ink viscosity is reduced as the ink temperature rises, a gap between the member 15 and the member 11 and a passage resistance formed by the nozzle 12 are reduced. As a result, pressure operating the ink near the nozzle is scarcely enhanced at the time of discharge of the ink, but since the gap between the members 15 and 11 is narrowed, the ink flowing resistance is increased to cancel to the pressure rise due to the increase in the resistance, thereby decreasing the variation in the pressure of the ink near the nozzle upon rising of the environmental temperature.

IPC: H01L21/8238
Filed: 1992-09-30
Abstract: PURPOSE: To provide a manufacturing method of an integrated circuit transistor which gives good protection from hot electron effect. CONSTITUTION: In an integrated circuit device, a mask is used for a drain 28 implantation and a hollow 26 implantation which are lightly doped. The mask exposes only the substrate adjacent to a gate electrode 20 of a field effect transistor. The hollow 26 implantation is performed only in the vicinity of a transistor channel, where the implantation achieves a useful function. The hollow 26 implantation is masked from an active region where the implantation is not necessary, so that the junction capacitance of the active region is reduced. The capacitance which is reduced in this manner improves the switching speed of the transistor. The mask to be used for defining the lightly-doped drain 28 and hollow 26 implantation regions can be formed easily by the combination of geometrical forms of the gate and the active region, which have already existed.
